摘　　要：用自定义特征的方法,介绍了管网建模系统的设计与实现。用基本图元生成特征矢量图标,给出矢量图标生成的过程和属性设置。在管网建模中,介绍了用矢量图标生成管网模型的建模步骤和实例。该系统与工程实际相结合,能够有效地提高管网建模的效率,具有管网建模的通用性和扩展性。整个管网建模系统采用面向对象的程序设计思想进行设计,扩展后可以作为相似行业的管网建模系统使用。Based on user-defined feature graphic system, a graphic system is designed, and it is used to build pipe net modeling. Vector icon is constructed by basic geometric elements and its attributes and the building process are given. Steps of building the pipe net mode- ling with the vector icon and a practical example are also described. The proposed system improve efficiency of the pipe net modeling. It is general and easily extended for the user-defined feature being used. This system is designed with object oriented programming technology, so it can be easily extended as the similar pipe net modeling.
